§Akka Persistence
§Persistence Plugin Proxy
A new persistence plugin proxy was added, that allows sharing of an otherwise non-sharable journal or snapshot store. The proxy is available by setting akka.persistence.journal.plugin or akka.persistence.snapshot-store.plugin to akka.persistence.journal.proxy or akka.persistence.snapshot-store.proxy, respectively. The proxy supplants the Shared LevelDB journal.
